im new to the forum and i own a 06 Evolution IX MR i have 380 whp and the tune is custom done by mzm and i had a question i just bought the tomei log turbo manifold because i blew up the JIC tubular manifold. Now when i went to order the cam gears from tomei they said that i only needed the exhaust side cam gear because the car has mivec. now the question i had for you evo gurus is this true do i only need one of the cam gears???

 

yes, mivec is valve timing that is always adjusting, so if you put on a cam gear and adjust it you will break your valves. im a tech at lexus and we had a kid up aem cam gears from a supra on his is300 well lexus has VVTI varible valve timing with intellagence, and he ended up having ot buy a new motor.

 

This is something I'm interested in as well.

So the Mivec only has one cam and cam gear??

 

evo's have 2 cam gears and 2 cams but you can only purchase the exhaust cam gear and you have to order the evo 9 mivec cams

 

Is it even needed/recommended to change the cam gear on a IX? I thought not.

 

i dont really know anyone that has changed out a cam gear on a ix, i seen one person on here that has

 

I did.

 

That must have hurt
